Bah, naturally I meant

  static_assert(!std::is_invocable_v<decltype(std::ranges::swap_ranges), std::ranges::subrange<cpp17_output_iterator<int*>>, std::ranges::subrange<int*>>);
  static_assert(!std::is_invocable_v<decltype(std::ranges::swap_ranges), std::ranges::subrange<int*>, std::ranges::subrange<cpp17_output_iterator<int*>>>);
